Eaton / Cutler-Hammer QCGFT2050 GFCI Miniature Circuit Breaker

This cable-in/cable-out breaker is designed specifically for Eaton Quicklag enclosures and custom OEM panelboards that accept QC-frame panel mount breakers. It is not compatible with standard plug-on or bolt-on residential load centers like the Eaton CH or BR series.

The QCGFT2050 utilizes a cable-in/cable-out mounting method, also known as feed-thru, rather than plugging directly into a panel busbar. It features box lugs on both the line and load sides and mounts directly to the backpan of compatible commercial enclosures.

The pigtail wire must be connected directly to the neutral bar inside your panel or enclosure. This connection powers the internal monitoring circuitry, allowing the breaker to accurately detect ground faults across the protected circuit.

This breaker provides Class A ground fault protection with a 5mA trip sensitivity. This level of protection is designed specifically to prevent severe electrical shocks to personnel in wet or damp environments.

Yes, current Eaton QCGFT series ground fault breakers feature an automated self-test mechanism. This internal function periodically tests the ground fault monitoring circuitry to ensure it is functioning correctly and complies with modern safety codes.

Yes, the QCGFT2050 serves as a direct, drop-in replacement for the discontinued QCGF2050. The letter T in the current part number indicates the addition of an automated self-test feature, but the physical dimensions, mounting, and core specifications remain identical.
